Product Overview

ASTM B622 is a standard specification for seamless nickel and nickel alloy pipes and tubes designed for corrosive service environments. Alloy C22 (UNS N06022), commonly known as Hastelloy C-22, is a nickel-chromium-molybdenum-tungsten alloy renowned for exceptional corrosion resistance. It is specifically engineered for heat exchangers operating in aggressive chemical and high-temperature environments.

Material Composition

Alloy C22's composition is optimized for performance in oxidizing and reducing media:

Nickel (Ni): ~56% (base element for ductility and corrosion resistance)
Chromium (Cr): 20-22.5% (enhances oxidation resistance)
Molybdenum (Mo): 12.5-14.5% (resists reducing acids and pitting)
Tungsten (W): 2.5-3.5% (synergizes with Mo for localized corrosion resistance)
Iron (Fe): 2-6%, Cobalt (Co): ≤2.5% (trace elements)
Carbon (C), Manganese (Mn), Silicon (Si), Sulfur (S), Phosphorus (P), Vanadium (V): Minimized to enhance weldability

Physical and Mechanical Properties

Tensile Strength: ~100 ksi (690 MPa)
Yield Strength: ~45 ksi (310 MPa)
Elongation: ~45% (excellent ductility)
Thermal Conductivity: 9.8 W/m*K (at 100°C)
Coefficient of Thermal Expansion: 12.2 μm/m*K (20-100°C)
Density: 8.69 g/cm³
Non-Magnetic: Suitable for sensitive applications

Industrial Applications

Heat Exchangers in Petrochemical Plants: Alloy C22's resistance to chloride-induced corrosion and its high-temperature strength make it suitable for use in heat exchangers in petrochemical refining processes, such as hydroprocessing, alkylation, and dehydrogenation processes.

Sulfur Recovery Units: In sulfur recovery plants, where acid gases like hydrogen sulfide and sulfur dioxide are common, Alloy C22 tubes are used in heat exchangers to prevent corrosion in these aggressive environments.

Pharmaceutical Manufacturing: Alloy C22's excellent corrosion resistance and biocompatibility make it suitable for heat exchangers in pharmaceutical and biotechnology applications. It can handle aggressive cleaning agents and sterilization processes.

Drug Processing: In drug manufacturing processes, Alloy C22 offers corrosion resistance, even in highly acidic or chloride-containing environments.
